The excess sulphur dioxide formed during the reaction is removed in another reaction tower. The resulting solutions contain moderate to high concentrations of hydrogen ions and have pHs of less than 7.0. The reaction is carried out in a steam-heated vessel. Acidic organic/inorganic salts, such as CHROMIC SULFATE, are generally soluble in water. CaF2 ( s) + 2H + (aq) Ca2 + (aq) + 2HF(aq) Example 18.7.1 shows how to calculate the solubility effect of adding a strong acid to a solution of a sparingly soluble salt. Na 2Cr 2O 7 + 3SO 2 + H 2O → 2Cr(SO 4)(OH) + Na 2SO 4 The net reaction of CaF 2 with strong acid is thus. The reaction can be represented as:Ĭr 2O3 + 3 H 2SO 4 → Cr 2(SO 4) 3 + 3 H 2OĪnother reaction, based on the same mechanism as above, for the production of basic chromium sulphate industrially is: Chromium, particularly in the hexavalent oxidation state, is toxic, hence basic chromium sulfate, which is comparatively less toxic, is preferred in the leather industry.īasic chromium sulphate is produced from the simple reduction of Cr (VI) to Cr (III) by the addition of an excess of sulphur dioxide. From Sciencemadness Wiki navigation search Chromium (III) sulfate is the inorganic compound with chemical formula Cr2(SO4)3. It is easily soluble in cold water and very soluble in hot water. Basic chromium sulfate has high tanning power and hence largely used in the tanning of leather. It is a green, odorless solid at room temperature.
